Diagnostic Test

WARNING: This page is about a different car, the 2014 Dodge Journey. However, it is still accessible from the selected car via links, so may be relevant.

CHECK IF PCM/TCM RELAY DTCS ARE PRESENT
1. With the scan tool, read DTCs
  Are there any Transmission Control Relay DTCs present also?
  
  Yes
  - Refer to the DIAGNOSTIC CODE INDEX and perform the appropriate diagnostic procedure.
  No
  - Go To 2
CHECK IF THE DTC IS CURRENT
1. With the scan tool, view DTCs.
  Is the status Active or is Starts Since Set counter set at 0 for this DTC?
  
  Yes
  - Go To 3
  No
  - Go To 8
CHECK THE PCM AND WIRING USING THE TRANSMISSION SIMULATOR
1. Turn the ignition off to the lock position.
2. Remove the Starter Relay.
  CAUTION:
  Removal of the Starter Relay will prevent the vehicle from being started in gear.
  
  WARNING:
  The Starter Relay must be removed from the PDC. Failure to do so may result in possible serious or fatal injury.
  
  NOTE:
  Failure to remove the Starter Relay can cause a Transmission - No Response condition.
3. Install the Transmission Simulator (special tool #8333B, Simulator, Transmission) and the Electronic Transmission Adapter kit.
4. Ignition on, engine not running.
5. With the scan tool, actuate the LC Solenoid.
6. Monitor the LC Solenoid LED on the Transmission Simulator.
  Did the LC Solenoid LED on the Transmission Simulator blink on and off during actuation?
  
  Yes
  - Go To 4
  No
  - Go To 5
CHECK WIRING USING THE TRANSMISSION SIMULATOR
1. With the scan tool, continue to actuate the LC Solenoid.
2. While monitoring the LC Solenoid LED on the Transmission Simulator, wiggle the related wiring harness and connectors.
  Did the LC Solenoid LED on the Transmission Simulator continue to blink on and off during the wiggle test?
  
  Yes
  - Replace the Transmission Solenoid/TRS Assembly in accordance with the Service Information. Refer to ASSEMBLY, TRANSMISSION SOLENOID AND PRESSURE SWITCH, REMOVAL .
  - Perform the 62TE TRANSMISSION VERIFICATION TEST. Refer to 62TE TRANSMISSION VERIFICATION TEST .
  No
  - Repair wiring or connectors as necessary.
  - Perform the 62TE TRANSMISSION VERIFICATION TEST. Refer to 62TE TRANSMISSION VERIFICATION TEST .
CHECK THE (T80) LC SOLENOID CONTROL CIRCUIT FOR AN OPEN

1. Turn the ignition off to the lock position.
2. Disconnect the PCM C1 harness connector.
3. Disconnect the Transmission Solenoid/TRS Assembly harness connector.
4. Measure the resistance of the (T80) LC Solenoid Control circuit between the appropriate terminal of the PCM C1 harness connector and the Solenoid/TRS Assembly harness connector.
  Is the resistance above 5.0 Ohms?
  
  Yes
  - Repair the (T80) LC Solenoid Control circuit for an open.
  - Perform the 62TE TRANSMISSION VERIFICATION TEST. Refer to 62TE TRANSMISSION VERIFICATION TEST .
  No
  - Go To 6
CHECK THE (T80) LC SOLENOID CONTROL CIRCUIT FOR A SHORT TO GROUND

1. Measure the resistance between ground and the (T80) LC Solenoid Control circuit.
  Is the resistance below 5.0 Ohms?
  
  Yes
  - Repair the (T80) LC Solenoid Control circuit for a short to ground.
  - Perform the 62TE TRANSMISSION VERIFICATION TEST. Refer to 62TE TRANSMISSION VERIFICATION TEST .
  No
  - Go To 7
CHECK THE (T80) LC SOLENOID CONTROL CIRCUIT FOR A SHORT TO VOLTAGE

1. Remove the PCM/TCM relay and with a fused jumper wire, jumper the Transmission Control Output to B(+).
2. Ignition on, engine not running.
3. Measure the voltage of the (T80) LC Solenoid Control circuit.
  Is the voltage above 0.5 of a volt?
  
  Yes
  - Repair the (T80) LC Solenoid Control circuit for a short to voltage.
  - Perform the 62TE TRANSMISSION VERIFICATION TEST. Refer to 62TE TRANSMISSION VERIFICATION TEST .
  No
  - Using the schematics as a guide, check the Powertrain Control Module (PCM) terminals for corrosion, damage, or terminal push out. Pay particular attention to all power and ground circuits. Check for Service Information Tune-ups or Service Bulletins for any possible causes that may apply. If no problems are found, replace and program the PCM in accordance with the Service Information. With the scan tool, perform Quick Learn.
  - Perform the 62TE TRANSMISSION VERIFICATION TEST. Refer to 62TE TRANSMISSION VERIFICATION TEST .
CHECK THE WIRING AND CONNECTORS
1. The conditions necessary to set the DTC are not present at this time.
2. Using the schematics as a guide, inspect the wiring and connectors specific to this circuit.
3. Wiggle the wires while checking for shorted and open circuits.
4. With the scan tool, check the Event Data to help identify the conditions in which the DTC was set.
5. Check for Service Information Tune-ups or Service Bulletins for any possible causes that may apply.
  Were there any problems found?
  
  Yes
  - Repair as necessary.
  - Perform the 62TE TRANSMISSION VERIFICATION TEST. Refer to 62TE TRANSMISSION VERIFICATION TEST .
  No
  - Test Complete.
